Title APPENDIX D Worked Example: Design of portal frame using elastic analysis 10 of 44 4 - 91 For orthodox single-storey portal frames, these expressions can be simplified as follows: y,Ed M = 0 and z,Ed M = 0 for Class 1, Class 2 and Class 3 sections. M z,Ed = 0 Therefore expressions (6.61) and (6.62) can be written as: 1,0 b,Rd y,Ed yy b,y,Rd Ed M M k N N and 1,0 b,Rd y,Ed zy b,z,Rd Ed M M k N N Expression (6.61) is used to verify in-plane buckling, and expression (6.62) is used to verify out-of-plane buckling.
